Answer 1

Let the no. b x
50percent of x=x/2
50+x/2=x
x=100

Answer 2

Greetings..!

Let the required number be x .

SO, 50 percent of x = (50/100)*x = x/2

According to problem , we need to add this to 50,and form equation :

⇒50 + (x/2) = x

⇒ 100+x = x      { taking L.C.M of 1 and 2 as 2 }

⇒100 = x-x

⇒100=x

Answer : Hence, the number is 100.
